A browser extension wallet is an add-on for your web browser that adds a cryptocurrency wallet to the browser's menu bar. Installing a browser extension wallet allows you to manage and trade cryptocurrencies and NFTs directly in decentralized apps like the GameStop NFT Marketplace, without ever having to leave your web browser window. Please read more here.

Install it from the Chrome Web Store, then open your extension tray (the puzzle icon next to your address bar), and "pin" the new GameStop Wallet icon that appears by clicking the pin icon. Click Create Wallet. Follow the on-screen steps from there. Please read more here.

A Secret Recovery Phrase is a sequence of words provided to you when setting up your new wallet. This phrase is the only way to recover access to your wallet if you forget your password or need to install your wallet again. Write it down immediately upon creating your wallet, and don't lose it. GameStop will never ask you for your Secret Recovery Phrase or Private Key. Please read more here.

To understand Layer 2, you should know what Layer 1 is first. Layer 1 is the base layer of the blockchain, also referred to as Ethereum mainnet. It often suffers from network congestion which causes high transaction fees and long delays. Layer 2 refers to a set of protocols created to solve this problem, operating on top of the blockchain, but importantly still part of that base network. Layer 2 provides faster speeds and lower transaction fees than the blockchain itself offers, while maintaining the security and trust of the Ethereum mainnet. Please read more here.

When you first create your wallet, it will immediately be able to transact on the Ethereum mainnet (Layer 1). In order to utilize the faster speed and lower fees of Layer 2, you'll need to activate your Layer 2 account, which you can do by depositing ETH to your Layer 2 balance.
